3 Claims. (chub-2'06) This invention relates to improvements in tobacco pipes. The draught or suction" of such pipes is frequently impaired through the clogging which takes place at the bottom of the pipe bowl,

and particularly at the junction of the bowl and the pipe stem, which clogging is due to continual accumulation o-f'various ingredients distilled out of the tobacco during the smoking. Those accumulated ingredients have to be frequently scraped out of the bowl, as, besides impairment of the suction, they also form hard or viscous masses which seriously vitiate the taste of the tobacco.

The principal object of the invention is to'provide a tobacco pipe with improved and efficient means for remedying the above mentioned disadvantages, to ease the conveyance of the smoke through the pipe, and to prevent the distilled objectionable ingredients of the tobacco from reaching the smokers mouth.

Another object is to provide a tobacco pipe having simplified, inexpensive, reliable, efiicient, and improved means for retaining an absorbent material ,for remedying said disadvantages, and for readily, rapidly, and conveniently discarding and renewing said material.

A further object is to efiect the improved distillation of objectionable ingredients from the tobacco within the pipe.

A still further object is to provide improved means for gaining access to'all the parts and surfaces in the region of the junction of the pipe bowl and stem, for the rapid, convenient,

and eificient cleaning of the same.

A still further object is to provide improved means for maintaining the pipe stem in clear state.

Other objects and advantages will hereinafter appear.

In the accompanying drawings, Fig. 1 is a longitudinal cross-sectional elevation of a tobacco pipe embodying the above referred improvements, and showing same as applied to a corn cob form of tobacco pipe.

Fig. 2 is a similar type view illustrating a modification of the improvements shown in Fig. 1.

The pipe I,Fig. 1, comprises'a bowl 2 of corn cob type and stem 3, the former having its bore 4 extending clear therethrough, from the rim 5 to the bottom 6. The upper or fire-pot portion or said bore has its wall I tapering downwardly,

then the wall continues vertically for-a comparatively short distance, as shown at 8, from there it again tapers for a short distance at 9, then it continues vertically as at portion l0, and from the latter the wall continues to the bottom as a narrower bore portion II. In the bore-portion i0 is removably seated a fitting 13 comprising a "flange ll serving as a floor for the fire-pot 1.

Upon ribs l5 of flange I4 is seated a tablet l9 made of any suitable material which will absorb objectionable ingredients 'from the burning tobacco. Said tablet is of frusto-conical configuration as shown, having a cavity 20 thereunder, and a plurality of smoke conducting passageways 2| are formed in the periphery of the tablet. A cap 22 having a cavity 23 slides upwardly into the.

bore. ll, thereby sealing said bore at the underside 6 of the bowl 2 and forming a chamber out of the bore-portion I I. There is provided a bored post 21 which is molded as shown in the cap 22 and itthreads at 28 clear through the fitting l3, whereby all these parts are efficiently held together and to the bowl 2, and maybe conveniently separated and reassembled for cleansing purposes; Openings 29 connect the bore l8 of post 21 with the chamber H. v The cap 22 is preferably provided with a gasket 30 to insure an air and smoke-tight fit against the underside B'oi.

the corn cob bowl 2. In the terminal 24 of stem 3 is removably fitted a tube 25 which projects into the chamber I l and is located above the cavity 23.

The tablet I9 is so dimensioned at its top-most or largest diameter that it fits snugly when passed through the straight-walled portion8 of the bore when insertedin the operative position shown, in which position it is consequently securely retained against dropping out during handling of the pipe when it is not smoked. As the pipe is used, the absorbent tablet l9 may be regularly renewed as it becomes Worn by merely breaking it, casting out the pieces, andv reinserting a fresh tablet in the above describedmanner, the arched cavity 20 facilitating the demolishing of the tablet. While the pipe is being smoked the tabflange l4 and between ribs I5 of fitting l3, up-

wardly into cavity 20, downwardlythrough the bore I8 of post 21, through the openings 29, into the chamber II, and-through tube 25 into the stem 3. Duringsaid passage of the smoke certain viscous objectionable ingredients not absorbed by the tablet l9 will be trapped in the the bore I8 and the openings 29, and drop into the cavity 23 and therein deposited. As smokers often cause their saliva to enter the stem, the

spaces between the ribs [5, and others not so trapped, such as solids, will be carried through same will be emitted through the tube 25 and likewise drop into the cavity 23. The spaces above flange l4 between ribs l5 may be occasionally cleaned out of its collected matter, and the receptacle 23 may be also conveniently cleaned out by merely unthreading the post 21 and thereby removing the cap 22.

In the pipe shown in Fig. 2, a grate 45 is seated upon an annular shelf 46 formed in the wall of the bore 4, and a bolt 47 molded in the cap 22 threads into a tapped opening 48 in the grate, whereby said parts may be disassembled and reassembled as required, and functioningin the above described manner. The end portion 49 of the stem-tube 25 is disposed obliquely and toward the receptacle 23, to facilitate exudation of any saliva being emitted from the stem 3 and depositing it directly into said receptacle.

Having thus described my invention, I claim: 1. In a tobacco pipe, the combination with a bowl and stem, said bowl having a perforated floor. a tablet of absorbent material located above the interior of said bowl having a vertical wall portion of a diameter corresponding to that of the top area of said tablet, a wall portion tapering downwardly from said vertical portion, and a wall portion tapering upwardly from said vertical portion, to insure a wedging fit of said tablet in said bowl.

2. In a tobacco pipe, the combination with a bowl and stem, said bowl having a floor with a tapped opening therein, said floor having a chamber thereunder extending clear through the bottom of the bowl, a cap carrying a threaded tube, attachable to and detachable from said tapped opening, the bore of said tube leading to said chamber, and said stern leading to said chamber.

3. In a tobacco pipe, the combination with a bowl and stem, said bowl having a floor with a tapped opening therein, said floor having a chamber thereunder extending clear through the bottom of the bowl, a cap for opening and closing the bottom of the bowl and said chamber, said L cap carrying a post extending from it and having a terminal threading into and out of said opening, and said stem leading to said chamber.
